This project is what is linked from the current sticky for Smash Melee. It appears to be abandoned since early 2011. For the information and in the service of those that come here through there I'll say the following:

For those looking for a Melee pack that aims to faithfully retexture the whole game, there's one in development at meleehd.boards.net.

Altogether, our team so far has put hundreds of hours of work into this. We have forum infrastructure, advertising blueprints, QA processes, professional standards, and outreach efforts. At the time this post was made we've done about 500 textures and plan to finish many more in the future.

hyperspeed, I realize that it's been a long time and you may no longer have interest in contributing to such a project. However, if you'd still like to see a Melee HD texture pack, we'd be happy to have you come help out.
